Margo I agree, I don't think anybody would want that job. Certainly not all those people who are doing the job, there's far too many for them all to be brainwashed into wanting to be there.
I wonder if that's part of why they are so aggressive? It does remind me of what we know of guards at concentration camps but also, if you're in such a toxic place against your own will, would you lash out at the people you were keeping there? Would you blame them for getting sent there, because they are the reason why you're also there to keep guard?
